ADJUSTING THE MAGENTA TT10 TURNTABLE
If you are a perfectionist, you may connect an oscilloscope alternately to
the left and right outputs of your preamplifier (or the Record Out
sockets), and check the bias adjustment by playing the test with separate
left and right channel signals, in various modulations, starting at 50 um.
The use of a Clamp makes it possible to choose a more precise downforce
and bias as the use of these gadgets do reduce distortion already to a
great extend. This will result in a better adjustment and a much better
signal.
